CHAPTER 8 EUCLIDEAN GEOMETRY BASIC CIRCLE TERMINOLOGY THEOREMS INVOLVING THE CENTRE OF A CIRCLE THEOREM 1 A The line drawn from the centre of a circle perpendicular to a chord bisects the chord. (line from centre ⊥ to chord) If OM AB⊥ then AM MB= Proof Join OA and OB.

Angles of a Circle. Angles in the major segment. Rule 1. According to this rule the angles made in the same segments are equal. OR. Angles made by the same chord in the same segment are always equal. Remember that there can be any number of angles but if they are in the same segment, they are always equal. Rule 2.

includes problems of 2D and 3D Euclidean geometry plus trigonometry, compiled and solved from the Romanian Textbooks for 9th and 10th grade students, in the period , when I was a professor of mathematics at the "Petrache Poenaru" National. We define a diameter, chord and arc of a circle as follows: Ł The distance across a circle through the centre is called the diameter. Thus, the diameter of a circle is twice as long as the radius. Ł A chord of a circle is a line that connects two points on a circle. Ł An arc is a part of a circle. The word geometry in the Greek Circles A circle can be de¯ned the set of all points that are equidistance from a point called the center of the circle.
